Ptolemaeus in Egypt Recognized but Expelled by His Subjects
On the other hand the brother who reigned in Egypt succeeded
in purchasing his recognition by decree of the people from the new
masters of Rome in 695; the purchase-money is said to have amounted
to 6000 talents (1,460,000 pounds). The citizens indeed, long
exasperated against their good flute-player and bad ruler,
and now reduced to extremities by the definitive loss of Cyprus
and the pressure of the taxes which were raised to an intolerable
degree in consequence of the transactions with the Romans (696),
chased him on that account out of the country.
When the king thereupon
applied, as if on account of his eviction from the estate which he
had purchased, to those who sold it, these were reasonable enough
to see that it was their duty as honest men of business to get back
his kingdom for Ptolemaeus; only the parties could not agree
as to the person to whom the important charge of occupying Egypt
by force along with the perquisites thence to be expected should
be assigned.
